在springboot项目中整合Druid

或

1.导入maven坐标
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.2.19</version>
</dependency>

2.在application.properties中配置连接池
spring:
  datasource:
    druid:
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://localhost:3306/test
      username: root
      password: 123456

总结：
